End-to-End Encrypted

Your data stays yours

Beautifully designed applications with absolute end-to-end encryption. No tracking. No data harvesting. Just privacy.

Privacy built into everything

Every feature is designed with your privacy as the foundation, not an afterthought.

Zero-Knowledge Encryption

Your data is encrypted before it leaves your device. We never see your plaintext — ever.

Private by Default

No tracking pixels, no analytics, no data harvesting. Your activity stays on your device.

Works Offline

All apps work offline. Sync when you're ready — no internet required for core features.

Open Source

Our encryption libraries and core apps are open source. Audit anytime, contribute freely.

Cross-Platform Sync

Seamlessly sync across all your devices. Encrypt locally, decrypt everywhere.

Simple & Beautiful

Enterprise-grade security with a delightful user experience. Privacy doesn't have to be ugly.

Security First

Encryption you can trust

We use battle-tested cryptographic primitives. AES-256-GCM for data at rest, PBKDF2 with 600,000 iterations for key derivation, and X25519 for secure sharing.

AES-256-GCM authenticated encryption
PBKDF2 key derivation (OWASP 2024)
X25519 ephemeral-static DH for sharing
96-bit random IV per encryption
Server never sees encryption keys
How E2EE works
1
Key Generation
Your password derives a Master Key locally
2
Local Encryption
Data is encrypted before it leaves your device
3
Secure Storage
Only encrypted blobs are stored on our servers
4
Private Decryption
Decryption happens locally — we never see plaintext
